Notes:

Rosa coriifolia var. froebelli or, if you prefer, Rosa canina froebelii, or Rosa dumetorum 'Laxa', is frequently referred to as 'Laxa' or Rosa laxa when used as understock. To complicate matters further, Laxa is not the true species R. laxa Retzius, which was used by Dr. N. E. Hansen to breed hardy roses.

Laxa was introduced as a horticultural cultivar in 1890 by Otto Froebel of Zurich, Switzerland. The species is distributed over much of Europe and Asia Minor. As a cultivar, Laxa may show less variability and more consistency than the species.
